Objective: The purpose of this study was to explore the influences of gestational age, the choice of fetal fluid compartment, and the algorithm for calculation on the estimation of the base deficit in umbilical cord arterial blood Lit birth. Study design: From 1995 to 2002, cord arterial blood gases and obstetric data were available for 43,551 newborn infants at 37 + weeks of gestation (cohort 1).
Females of many songbird species show a preference for mating with males that have larger song repertoires, but the advantages associated with this preference are uncertain. We tested the hypothesis that song complexity can serve as an indicator of male quality because the development of the brain regions underlying song learning and production occurs when young birds typically face nutritional an
Maximal utility of accessible data is attractive to all partners in clinical research, whether it directly improves patient care or more accurately allows identification of the safety and efficacy of a new drug or procedure. The Food and Drug Administration (FDA) has presented a guideline draft addressing digitization of electrocardiogram (ECG) data in clinical trials to improve the standards for
Abstract in Undetermined BACKGROUND: Testicular cancer (TC) patients have a high survival rate, and the question of post-therapy recovery of sperm production and its dependence on genetic predisposition is of major interest. METHODS: Ejaculates were obtained from 112 TC patients at one or more of the following time points: post-orchidectomy, or 6, 12, 24, 36 and 60 months post-therapy. The lengths
Purpose: Histologic grade, Nottingham Prognostic Index (NPI), estrogen receptor (ER) and progesterone receptor (PSR) status, and tumor size have previously been shown to be important prognostic indicators for distant recurrence of breast cancer. The purpose of this study was to compare the prognostic value of these factors with flow cytometric S-phase fraction (SPF), urokinase plasminogen activato
In order to elucidate the composition of the female sex pheromone of the northern (beech) winter moth, Operophtera fagata Scharf. (Lepidoptera: Geometridae), ovipositor extracts of unmated, calling females were analysed by gas chromatography with simultaneous electroantennographic and flame ionization detection (GC-EAD/FID). Male antennal responses indicated three active components, two of which h
The hemY gene of the Bacillus subtilis hemEHY operon is essential for protoheme IX biosynthesis. Two previously isolated hemY mutations were sequenced. Both mutations are deletions affecting the hemY reading frame, and they cause the accumulation of coproporphyrinogen III or coproporphyrin III in the growth medium and the accumulation of trace amounts of other porphyrinogens or porphyrins intracel
Two subspecies of Nigella degenii (Ranunculaceae) possess a dimorphism in pollen colour and vary extensively in frequency of the two morphs in natural populations. Here we investigate the role of selection on pollen colour during the pollination phase in the two subspecies and its potential contribution to the maintenance of this colour variation. In a combination of common garden experiments and
Predicting the risk of future events is an essential part of health economic simulation models. In pursuit of this goal, the current study aims to predict the risk of developing first and second acute myocardial infarction, heart failure, non-acute ischaemic heart disease, and stroke after diagnosis in patients with type 2 diabetes, using data from the Swedish National Diabetes Register.
The increasing spread of global pandemics such as HIV/AIDS, tuberculosis (TB) and malaria, in particular in developing countries, has forced the engagement of industrialized countries and pharmaceutical companies. Because medicines to cure these diseases are often under patent protection, they are not affordable for people in developing countries where health crises prevail. In November 2001, WTO
Germany’s current energy grid was built to match energy production from major power plants (coal, gas, nuclear). Due to the 2011 decision to exit all nuclear power until 2022 and ambitious national CO 2 reduction targets, the need to modernise and extend the grid has received substantial attention. In the past, implementation of grid extension projects had shown to be slow and raise serious pu
Förändras mikroorganismers ”samhällsstrukturer” över säsongen? Överallt i marken finns det mikroorganismer som servar växterna med näring, både i form av att de hjälper till att ta upp näring och dela med sig av, och genom att de bryter ner dött material och därmed gör näring tillgänglig. Jag har ställt mig frågan om mikroorganismer i jorden varierar i mängd, sammansättning och aktivitet över säAbstract Seasonal variation in microbial community composition was investigated from early spring tillautumn alonga sandy grasslandslope with variation in soil moisture, vegetation composition and nutrient availability.The testedhypotheses were:(1) the microbial community composition will change with theseason,(2) microbial biomassis highestin spring,(3) saprotrophic fungi will be more abundantin
Hydroelectric power is a controversial renewable energy. Adding more renewables to the energy mix is becoming more critical with the onslaught of climate change, while river health and water quality remain a highly pertinent environmental issue. Balancing the need for local renewable energy and environmental concerns is the topic of many cases. This thesis analyzes a case of conflict surrounding t
I svensk rätt finns i dagsläget ingen bestämmelse om allmän skyldighet att bistå nödställda. Frågan har, historiskt sett, behandlats i utredningar och flertalet motioner har lagts fram men alla har gått i avstyrkande riktning. I brist på en straffsanktionerad hjälpplikt kan enskilda trots förmåga och hjälpmedel välja att inte ingripa utan att straffas. Lagstiftaren menar att försiktighet måste iak
Global dependence on fossil fuels encourages the depletion of non-renewable resources, produces greenhouse gas emissions, and ultimately contributes to anthropogenic climate change. Current efforts do not reduce depletion rates of these non-renewable resources despite collective action to improve long-term sustainability of Norwegian energy governance in the Barents Sea. This study focuses on the
This paper presents a search for physics beyond the Standard Model targeting a heavy resonance visible in the invariant mass of the lepton-jet system. The analysis focuses on final states with a high-energy lepton and jet, and is optimised for the resonant production of leptoquarks — a novel production mode mediated by the lepton content of the proton originating from quantum fluctuations. Four di
Purpose: Radiotherapy (RT) for patients with locally advanced head and neck squamous cell carcinoma (LA-HNSCC) can be intensified by delivering 6 (6fx/w) instead of 5 (5fx/w) fractions per week. Randomized trials have demonstrated superiority for 6fx/w in patients treated without concurrent chemotherapy (CRT). This real-world analysis compares 6 vs 5 fx/w in LA-HNSCC all-comers, treated predominan
BACKGROUND/AIMS: This study represents an external validation with model updating of the online DIGIROP-Prescreen and DIGIROP-Screen 2.0 prediction models, incorporating ≥14 days of parenteral nutrition as an additional predictor, to identify infants requiring treatment for retinopathy of prematurity (ROP) in a contemporary Swedish cohort, estimate potential cost savings and compare DIGIROP perfor
